When is periodic maintenance?

In order to add new features or make performance upgrades, we perform periodic maintenance every day from 4:00 AM to 4:10 AM (JST) (the start and end times of maintenance are subject to change).

During this time, a portion of services will be unavailable for the Bitcoin Exchange and bitFlyer Lightning. We apologize for the inconvenience during these times.
The following features and services will still be available during maintenance.

1. Login
You can still log in as usual.

2. The Bitcoin Exchange and bitFlyer Lightning
• New orders will not be taken. Orders will not be executed.
• Once the maintenance has been concluded, the Itayose method will be implemented for 2 minutes to determine the price for resuming trading.
• Orders placed before maintenance can still be canceled. However, the reflection of the cancelation may be delayed.
• Should any special orders be triggered just before maintenance, there is the possibility that they will be executed once the service resumes. If the service resumes under the Itayose method, the order will use the corresponding Itayose method.

3. Other services
Services other than the Bitcoin Exchange and bitFlyer Lightning (including the Bitcoin Market, Altcoin Market, deposits and withdrawals of JPY or virtual currency, Earn Bitcoin, and Bitcoin Bazaar) will operate as usual.

* The services available or unavailable during maintenance are subject to change.

Most frequently asked questions

In order to provide a secure service to our customers, we have measures to prevent unauthorized logins and use. We also support additional measures on the customer side.
The following additional security measures are available for our customers.

• Two-factor Authentication

You can enable two-factor authentication through SMS, email, or authentication apps.
*We recommend using an authentication app for stronger security.
You can strengthen the security of your account by requiring a 6-digit authentication code in addition to your email address and password.
To enable two-factor authentication, log in to bitFlyer, select Settings, and then Security Settings. From there, you can enable two-factor authentication.

• Confirm Your Login History

Whenever your account’s email and password are entered to log in to bitFlyer’s services, the date, time, location, and device used are all recorded on the Login History page.
To see your login history, log in to bitFlyer, select Settings, and then IP Address / Login History.

• Enable Login Alerts

If you enable login alerts, you’ll receive an email every time your bitFlyer account logs in.
To enable login alerts, log in to bitFlyer, select Settings, and then Security Settings. From there, you can enable login alerts.
*If you receive an unexpected login alert or have a login you do not recognize in your login history, it could mean that your email address and password have been stolen by a third party. If you suspect that a third party has logged in to your account, please change your email address and password immediately.

• Set a Complex Password

Do not set a simple password or one that uses common combinations of characters (12345678, asdf, 1980, password), your name, telephone number, or birthdate.
To make a password that is difficult to guess, ensure that is at least nine characters with a combination of capital letters, lower case letters, numbers, and symbols so that it has an appropriate length and complexity.
To change your password, log in to bitFlyer, select Settings, and then Change Password.
Unauthorized access has been happening on many services recently. To improve security, do not use the same password for other websites and services.

• Keep Your OS and Apps Updated

Operating systems and apps may contain bugs or design mistakes that cause flaws in information security called vulnerabilities.
If these vulnerabilities remain, they come with the risks of unauthorized access and viruses. Even if a vulnerability is fixed, a new vulnerability could be discovered. Therefore, it is advisable to regularly check for and install updates to your OS and apps.

• Install Security Software

The number of viruses and fraudulent websites that can steal information from PCs and smartphones is on the rise.
We recommend installing security software on your devices to increase security.

JPY withdrawals requested before 2:50 PM (JST) on business days will generally be processed on the same day. If the JPY withdrawal request was made at or after that time, it will be processed on the next business day. It is possible for withdrawals to be delayed by the bank’s processing status.

* There is a possibility of delays in processing times for banks on days such as the fifth and tenth day of every month, the start of every week, the day after national holidays, or the end of the month.

Important Notes:

Some banks may differ in how long transfers take to process and some may process transfers on the next business day. Please make inquiries to each bank about the status of transfers.

In the event of an account having service restrictions in place or if the name on the bank account used in the transfer differs from the name on the bitFlyer account, the deposit may be delayed or unable to be deposited to your account.

Deposits may face delays or may not be able to be deposited quickly due to weekends, national holidays, system maintenance times, etc.
